Focuses on the transition from counting by ones to unitizing ten as a single group. Students use bundles and frames to see '10' as both ten ones and one ten.
A K-2 math lesson focusing on solving addition and subtraction word problems using part-part-whole mats, bar models, and number lines, while applying counting on/back and making-a-ten strategies.
This lesson introduces addition within 20 through the 'Make Ten' strategy and Number Bonds. Students progress from using physical counters to visual ten frames and finally to abstract equations.
A comprehensive introduction to 3D geometric shapes including cubes, spheres, rectangular prisms, cones, pyramids, and cylinders. Students will learn to identify these shapes, count their attributes (faces, edges, vertices), and find them in the real world.
A fun, monster-themed lesson focused on identifying and naming numbers 1-20 through a hands-on 'Roll and Cover' game. Students practice subitizing and number recognition in a playful, low-stakes environment.
A comprehensive math review lesson designed to reinforce key elementary math skills including logical ordering, 2-digit subtraction, geometric attributes, and equal parts/fractions. This lesson uses a repeated "at-bat" structure to build mastery through multiple variations of the same problem format.
A math review packet focusing on basic addition, subtraction, number combinations, and visual representation of groups, including a student worksheet and an answer key.
A 3-day lesson series covering the partitioning of circles and rectangles into equal shares (halves and fourths/quarters) through baking.
A focused lesson on identifying missing addends within 20 using number bond visual representations to build algebraic thinking and fluency.
A magical math lesson where students count, sort, and graph different types of ponies to practice data representation and comparison skills.
A cumulative review of 2D/3D shapes, positional words, and measurement comparisons to assess mastery.
Students identify 3D shapes (cube, sphere, cone, cylinder) and compare objects based on size and length.
Students identify 2D shapes (circle, square, triangle, rectangle) and use positional language (over, under, beside) to describe location.
Students analyze input-output tables to identify constant addition or subtraction rules and apply those rules to find missing values.
